This is what I have found to be typical of ST Engines. An appology response & a promise W/no further contact.

It has been over a month since the above post W/O any further contact when questions are raised.

The same as what I experienced W/e-mails.

It's a shame really as they seem to have some interesting products. I was very interested in the regulators thay claimed would allow gasoline to be used W/the stock glow fuel carb. I sent numerous e-mails to no avail. I also liked their saito trigger ring/hall sensor set-up (as pictured on their site) better than any others I have seen.

I don't see how they atre able to sell any product W/such dismal comunication.
